A dedicated labeling coil for arterial spin labeling (ASL) technique can alleviate the challenges at 7T MRI, in this work we propose a separate 16-channel RF neck coil for transmit only. Finite-difference time-domain (FDTD) simulations and RF shimming have demonstrated the feasibility of this design to produce a homogeneous B1+ fields in the labeling region (left and right common carotid arteries) while minimizing SAR to within safe limits.
